39、ction of “high pressure vessels” which are in general above 10,000 psi. This was based on recommendations made by the Operations, Applications, and Components Technical Committee of the ASME Pressure Vessel and Piping Division. “ASME Section VIII, Division 3 Alternative Rules for Construction of Hig

40、h Pressure Vessels” was first published in 1997. The Committee continues to refine and develop the Standard to this day. Some of the innovative concepts which began with ASME Section VIII, Division 3 include: Use of elastic-plastic finite element analysis in design of pressure equipment One of the l

41、owest design margins which was originally published at 2.0 and then lowered to 1.8 Use of high strength materials for the pressure equipment used in manufacture of high pressure equipment Stringent requirements on fracture toughness for materials used in construction Complete volumetric and surface

42、examination after hydrotest The use of fracture mechanics for evaluation of design life assessment in all cases where “Leak-Before-Burst” cannot be shown Consideration of beneficial residual stresses in the evaluation of the design life of vessels ASME contracted with Structural Integrity Associates
